Gravity Forms Redirect URL in New Tab

This number 4 I want to sue. And this gives code to make it happen. I am asking where to insert the code that is provided here:

Thanks @EwingWorks. That is PHP code which can be added to your theme functions.php file, or you can use a plugin such as this one to keep the code separate from the theme: Code Snippets – WordPress plugin |

If you have any other questions, please let us know.
